Question

1. We want to compute the following matrix product. $\begin{bmatrix} 2 & 0 & 1 \ -1 & 1 & 1 \ \end{bmatrix} \begin{bmatrix} 1 & 3 \ 4 & 6 \ 2 & 5 \ \end{bmatrix} = \begin{bmatrix} c_{11} & c_{12} \ c_{21} & c_{22} \ \end{bmatrix}$ (a) To find $c_{21}$, which row of the first matrix must be multiplied by which column of the second matrix? What is $c_{21}$? (b) Find the product.
